As electrons travel towards NADP+, they generate a proton gradient across the thylakoid membrane, which is used to drive synthesis of ATP. Thus NADPH, ATP, and oxygen are the products of the first phase of photosynthesis called the light reactions.
Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Assertion and Reason Explanation:

Assertion: During photophosphorylation light energy is utilized to produce the proton gradient that is required for ATP synthesis.

Reason: Oxidative phosphorylation results as the energy of oxidation-reduction is utilized for phosphorylation.

Explanation:
- Photophosphorylation: In photophosphorylation, light energy is used to drive the electron transport chain in the thylakoid membrane of chloroplasts. This process generates a proton gradient across the membrane, which is then used by ATP synthase to produce ATP from ADP and inorganic phosphate.
- Oxidative phosphorylation: Oxidative phosphorylation occurs in the mitochondria and involves the transfer of electrons through the electron transport chain, leading to the pumping of protons across the inner mitochondrial membrane. The energy released during this process is used to drive ATP synthesis by ATP synthase.
- Relation between Assertion and Reason: While both Assertion and Reason are true, Reason is not the correct explanation of the Assertion. Photophosphorylation and oxidative phosphorylation are two distinct processes that utilize different sources of energy (light energy in photophosphorylation and energy of oxidation-reduction in oxidative phosphorylation) to generate ATP.
Therefore, option 'B' is the correct choice for this question.
